Patent CA-2032397-A1 (CA)
Inventor: WELTER HUBERT
IPC: B29B17/02
Filed: 1990-12-17
Abstract: The invention relates to a method and plant for the disposal of partialy dismantled refrigerators, especially for the disposal of chlorofluorocarbon-containing polyurethane foam. 
<??>The partly dismantled refrigerators are introduced into a disposal plant which can be sealed gas-tight, can be operated under a vacuum and can be evacuated at a number of points, and comminuted in a comminution plant. The materials adhering to the PUR foam are mechanically separated off. The residue-free PUR foam is ground to a powder, the cells of the PUR foam being destroyed and the bound chlorofluorocarbon-containing blowing gas being released. 
<??>The residues and PUR powder are collected separately, and the chlorofluorocarbon-containing gas obtained on comminution and grinding is liquefied. 
<??>The advantages achieved by the invention are especially that the disposal of the refrigerators supplied is complete, more than 99% of the chlorofluorocarbon-containing gas being liquefied and recycled together with the other recovered materials.

Title: Spring biased valve for use in a positive displacement volumetric pump
Inventor: LAWLESS MICHAEL W
IPC: F04B53/10
Filed: 1991-03-14
Abstract: A SPRING-BIASED VALVE FOR USE IN A POSITIVE DISPLACEMENT VOLUMETRIC PUMP                 Abstract of the Disclosure A "cracking valve" for use in a volumetric pump. A volumetric pump (30) includes a plunger (48) for compressing a pumping portion (34b) of a flexible tubing that extends through the pump. An inlet cracking valve (46) and an outlet cracking valve (52) are disposed so that they compress the flexible tubing to control fluid flow therethrough. The inlet cracking valve operates in three modes, including a fully open mode, a closed mode that stops fluid flow through the flexible tubing, and a cracking mode. The outlet cracking valve only operates inthe closed mode and the cracking mode. As the plunger compresses the flexible tubing, fluid pressure within the pumping portion of the flexible tubing initially builds until it exceeds a predefined cracking pressure, forcing open the inlet cracking valve, which is in its cracking mode, so that excess fluid is forced back to a container (32). After the pumping portion of the flexible tubing is compressed to a predefined volume, fluid at the cracking pressure is forced through the outlet cracking valve, which is then in its cracking mode. To compensate for changes in the elasticity or stiffness of the flexible tubing, balance blocks (42, 58) cooperate with the inlet cracking valve and the outlet cracking valve, respectively. The balance force developed by the balance block as a function of the stiffness of the flexible tubing is added to the force of 8 cracking flexure to produce the desired predefined cracking force at the inlet cracking valve and the outlet cracking valve. A "T-shaped" formation comprising a transverse ridge (166) and a longitudinal ridge (168) comprises valve faces (106a, 106b) at both cracking valves. The transverse ridge controls fluid flow, whereas the longitudinal ridge has a surface area over which the fluid pressure within the pumping portion of the flexible tubing acts to overcome the cracking force.

Title: Defect correction for ccd and cid imagers
Inventor: PAPE DAVID D
IPC: H04N5/367
Filed: 1991-03-22
Abstract: Title:  DEFECT CORRECTION FOR CCD AND CID IMAGERS ABSTRACT OF THE INVENTION:         A defect correction apparatus for a solid state imaging  device  employs  a  frame  buffer  responsively coupled to the imaging device for storing digital values of shuttered dark pixel data from image locations of the imaging device.  A register responsively coupled to the imaging device and having an output coupled to the frame buffer sequentially clocks digital values of image pixel data of the imaging device into the frame buffer.   A comparator having an output operatively coupled to the register and being responsively coupled to the dark pixel data of the frame buffer produces enable and inhibit outputs.  When any selected element of dark pixel data is less than a threshold, indicative of an operative pixel element  in  the  imaging  device,  data stored  in  the register corresponding to the pixel is stored in the frame buffer in response to the enable signal.  When the value of the dark pixel data in the frame buffer is greater than the threshold the comparator produces all inhibit signal.  The value of image data of a previous operative pixel  element  is  thereby entered  into  the register and frame buffer.

Patent CA-2045547-A1 (CA)
Title: Process
Inventor: WILMOTT MARTYN
IPC: C07C31/125
Filed: 1990-01-16
Abstract: A process is described for separating fatty alcohols from a fatty alcohol fraction which contains a minor amount of a lower alkyl (e.g. methyl) fatty acid ester or esters. The fatty alcohol fraction is subjected to transesterification to convert substantially all of any lower alkyl ester present to wax ester or esters. The resulting lower alkanol (e.g. methanol) is evaporated. Then the intermediate transesterification mixture is distilled to recover fatty alcohols. The residue from this distillation step is mixed with excess lower alkanol and again transesterified to reconvert wax ester or esters to lower alkyl esters. This mixture is re-distilled and the recovered mixture of lower alkanol and fatty alcohol or alcohols can be recycled. If an alkyl titanate is used as transesterification catalyst then both distillation steps can be effected without prior separation of the catalyst and the non volatile residue from the second distillation step can be recycled to the first transesterification step.

Title: Coal-water mixture using upgraded low-rank coal and process for producing said mixture
Inventor: YOKOKAWA CHIKAO
IPC: C10L1/32
Filed: 1992-06-24
Abstract: ABSTRACT OF DISCLOSURE        The present invention provides a process for producing a coal-water mixture using a reaction mixture obtained by subjecting a low-rank coal of high water content to a hydrothermal treatment in the presence of carbon monoxide and water at a temperature not higher than the critical temperature of water.  The above hydrothermal treatment makes the walls of pores present in the coal hydrophobic and densifies the coal matrix, whereby the coal after the treatment has a lower equilibrium moisture content.  Hence, it becomes possible to produce a coal-water mixture containing a high concentration of coal and having good stability and fluidity, from a low-rank coal of high water content which has been unusable as a material for a coal-water mixture.        Further, in the production of a coal-water mixture from the above reaction mixture, the amount of surfactant used can be reduced because the liquid phase of the reaction mixture contains a large amount of humic acid having surface activity.
